Santini Gravel Delta is a loose-fitting jersey ideal for cycling on hot summer days. It features a snug fit and is made entirely from recycled Polartec® Delta fabric, which has excellent thermoregulatory properties. Delta™ works more efficiently thanks to raised contact points, increasing airflow, dispersing moisture faster and reducing moisture cling. There are also two inner back pockets that close with small zippers, so you can take the essentials with you.
